Q
query
A keyword, group
of keywords or phrase, with or without special instructions like Boolean
operators, used in a search. In simpler
terms, it is that which the user enters into the search box. It is what
the search engine compares documents
to in order to return only relevant
documents.
query-by-example
/ find similar
Many search engines
have a "find similar" feature that allows users to request
documents the search engine considers similar to the document the user
specifies.
query expansion
/ search within results
The process of basing a new query
on an old one. Many search engines
allow users to "search within these results".
Additional Information:
The process of adding similar words to a query
in such a way that recall and precision
improve. Expansion is done mostly in the background using thesauri or
other linguistic resources.

quote(s)
When used in a search,
the quote marks ' " ' tell most systems that you only want to see
matches that are exactly like what you are
asking for. For example, a search for 'electric light', entered without
the single quotes, will return much different results than "electric
light" entered with the quotes as shown.
